Thisinvention relates to terminal disconnectors for wet batteries such as are commonly used in motor vehicles, and the main object is to provide means of a novel and I practical nature for gripping the terminal coupling and forceably removing it from the battery post or terminal, to which such couplings frequently become so tightly fastened that ordinary methods will not effect the disconnection which is necessary, for instance, when the battery is to be removed from the car. Further and more specific objects will be disclosed in the course of the following specification, reference being had l5 to the accompanying drawing, in which:

Fig. lis a plan elevation of one side of the device, showing it in an open position. Fig. 2 is a similar elevation of the other side of the device, showing it as in a gripl0 ping position on the battery terminal.

Referring to the drawing more particularly and by reference characters', A designates one handle and B the other handle of a pair of tongs, which are pivotally connected, as at C, and are provided with gripping jaws D and E, adapted to grip the terminal coupling F, to which is secured the usual cable G. The coupling F is secured upon the slightly tapered post H, of the battery head n J, and is usually of thesplit ring type having a clamping bolt (not shown) for tightly gripping it upon the post.

Pivotally secured, as at K, to the tong or lever B, is a third handle or lever L, which u is substantially parallel with and adjacent to the lever A, and `has a'lever acting stud or finger M arranged to operate substantially midway between the jaws D andE. The levers A and L are recessed, as at N, for' the 4 reception of the lever B, and lever B, in

turn, is recessed as at O, to receive the narrowed portions of the levers A and L, so that all three levers will. operate in the same plane, and the entire device will not be thick- 5 er than the `width ofany one of the levers. It may also` be noted that the projection or finger M extends in a shoulder P, under the lever B, and thus acts as a stop for the outward swinging movement of the lever or handle L.

To remove a terminal coupling such as F, the jaws D-E are firmly gripped upon it, as shown in Fig. 2; a retaining ring' is then moved up on the levers A-B to hold the jaws tightly in place. The operator then extendshis hand over the levers L andk B, and `by compressing them forces the 1inger M down upon the post H, thus lifting the coupling fromthe post. If the first lift does not fully release the coupling then it is a simple mattertosecure a second and lower grip on the coupling and thus effect a second lift.

It is understood ythatsuitable modifications may be made in the general design' and structural detailsof the'device, as shown in the drawings, provided, however that such modifications come within the f spirit and scope of the appended claims. Having now therefore fully shown and described our invention, what we claim to be new and desire to protect by Letters Patent is: j f

l. The combination with a pair of tong levers having substantially parallel, spaced ,y jaws provided with opposed gripping teeth,

of a `third lever pivotally secured to one of the tong levers and having an operating finger adapted to be moved substantially endwise and longitudinally between the jaws of the tongs. Y s

2. The combination including three levers, two of which are pivotally connected to the third, two of said levers having substantially parallel, spaced. opposed gripping jaws and the third lever having a blunt extension 'operating substantially between said jaws to push an object outwardly from therebe` tween. e

3. The combination including three levers two of which are pivotally secured to the third, two of said levers having substantially parallel opposed gripping jaws and the third lever having an extension operating substantially longitudinally between said jaws to press an object outwardly from, therebetween, two of said levers being recessed to receive the third lever, and such third lever being recessed to receive the other two levers.

4. A device of the character described consisting of ya pair of tong levers pivotallyl f connected and having opposed, substantially parallel gripping jaws, means for releasably engaging the levers to hold said jaws upon an object gripped thereby, a finger member operatively associated with and between said jaws for removing an object outwardly from therebetween, and a third lever for operating said finger member.

5. A device of the character described lll consisting of a pair of tong levers pivotally connected und having opposed 4gripping jaws, means for release-bly engaging the levers to hold said jaws upon an object gripped thereby, L finger member operatively associated with sziid ljaws so as to move substantially longitudinally of and. outward ly therebetween, and a third lever for operatingsaid finger member, said third lever extending adjacent to .and substantially par- 10 nllel nwith onel of' the tong levers.

In testimony whereof We alix our signatures.
